Prolly you know electer (he's the biggest nit on the network)
he's line is ultra strange ...! he cbets a lot and when he don't cbet he always give up ....

I know that the call here vs him and with this info is very marginal (specially oop)....but here he's repping exactly 44 and nothing else I guess ...he's not going to play Ak this way ...
so fold or call on the turn ... and what about the river?

ive never seen villain

i think if u know he is always giving up here i would check the turn. give hima chance to catch something or try betting. no matter how nitty he is its easier for him to bet or call 1 street when in position. So u always think aobut max value, if max value is u getting one street here, then its best to wait until the river

and esp at lower limits, a nit is a nit, doesnt matter how narrow a range he is repping. so a call here is fine and c/f river but if this rr on turn always = betting river and he always has it, well then u gotta fold turn
